To aZZ whom it may concern.-

Be it known that I, WALTER WAGNER, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Can-Body Side-Seam-Soldering Machines, which are fully set forth in the following specification, reference being bad to the accompanying drawings, forming a part hereof, and in which- Figure 1 shows a central vertical section of my can-soldering machine, showing, principally, the parts attached to the central shaft and one mandrel and former open to receive a can-body and the other closed and in the act of soldering the side seam of a can-body. Fig. 2 shows a central vertical section taken at right-angles to that of Fig. 2. The central shaft is not in section. It also shows the posts which supportthe mechanism and their connections Fig. 3 shows myv said device in plan view, all parts above the wheel, 01, being removed. Fig. 4 shows the mandrel and open former with its operating mechanism in end view. Fig. 5, shows a mandrel and its supporting bracket in side view.

Like letters of refereucedenote like parts. The object of my invention is to solder, by machinery, the side seams of can-bodies in continuous circular motion, and to attain said desirable result I construct my said new device in substantially the following manner, namely:

Centrally, on a circular table, a, supported on posts, I), held together at their topby a.

spider b, is placed a vertical shaft, 0, pivoted in said spider, and actuated by a worm-gear, c, driven by a pulley, c Centrally to and on said table is bolted a flanged hub or tubular guide, a, extending down through it to the gear, a, and up to the hub of a wheel d. Said wheel, d, carries a series of, fixed centrally and longitudinally slotted mandrels d, tangent to a circle with axes in the plane thereof. The ends of said mandrel are parts Fig.

of brackets which are bolted to the wheel, (1. Through lugs, (1 on wheel, d, passes a rod, d on which are hinged side-pieces, d", and between said sides are hinged wings, or formers, e. The sides, d, are connected by a bar 61 having a roller, (1 which runs on a circular track, f, having a cam-shaped surface, and, in lugs, d, on the outside of the sides d, are reciprocatin g rods, g, which carry on their outer ends a head, g, having 2. depending spur with a roller, 9 and on its inner side, a shelf, 9 On the upper and inner edges of the sides, 01 are offsets with stops, h, and near the rear end of the sides d is a transverse stop, h. The vertical part of the head, g, and its shelf, 9 together with said offsets and stops, it and it, serve to receive and hold in proper place the flat sheet for forming the can-body. Cams, e, a, form a part of the Wings, 6, and on each side of their hinge-centers, are actuated by rollers, e, in the ends of forked levers, e Said levers are f ulcrumed between their ends on shafts d, in the sidep1eces, d The lower ends of said levers have rollers, e turning on the axes of said levers, and moving in slotted cams, t, on each side of the track, f. Said cams, t', approach and recede from each other and thus cause said levers to oscillate and move the cams, e, e, and thus open and close the formers, or wings, e, about the mandrel (1.

When a fiat can-body is placed, as aforesaid, the mandrel, d, cross-bar, (l and sides, 01, are apart, as shown on the right hand side of Fig. 1, the cam, f, being low at that part of its circle. As said parts advance, the track, f, r1ses and thus it raises said bar d and wings e, up snug against the mandrel, (1. At the same time the cam-shaped tracks 2' approach and thus cause the formers, e, to close, as shown on the left hand side in Fig. 1, where the can-body is formed and held between the mandrel and its formers ready to be soldered. The free ends of said formers, when closed, are apart far enough to admit the application of asoldering-bit on the joint of the can-body.

When the head, g, has been moved to its extreme outer position by means of the cam, 9 and roller g ,--im1nediately under the arrow-F1g. 3,-the fiat can-body is laid on the shelf 9 against the head, 9', and between the stops, h. In its onward motion the cam, 9 pushes the head and its can-body inward unt llt gets to its next, and extreme inward position, 2, where the can-body meets the stop, h. At this point the bar, (1 begins to hold said can-body, then the head, g, again moves outward, somewhat abruptly, from, 2, (Fig. 3) to give room for the former, e, under it, to rise. The cams, t', and levers, (2 now begin to close the formers, e, on the mandrel. As soon as they are closed said mechanism passes under a roller, 0, on a shaft in atrunnioned sleeve held by an arm, 0', attached, at the proper place, to some part of the frame or other suitable part of the machine.

Said

roller serves to lay the lapping edges of the can-body flatly upon each other. Its plane of motion is limited by the slot, 0 and spline, 0 A spring to give yielding pressure is be tween said sleeve and roller, 0, and set nuts, or an equivalent device holds its outer end on said sleeve.

Beyond the roller, 0, on arm, 5, fixed to a suitable support, is the mechanism for supplying powdered rosin to the joint to be soldered. It consists of a wedge-shaped box, 3, with a worm, in its sharper end having a spout, s parallel to the joint to be soldered. Said worm turns on its axis by bevel gears, .9 of which the larger wheel is held on a shaft in a right-angled arm, .9", of said box, and said shaft has, at its other end, a gear-wheel, s

actuated by a gear-wheel, s, also held by said arm, and above said wheel and on its shaft, is an arm, 8X, having a pivot at its outer end on which turns the gear, 3 which meshes into, 8 and to it is fixed the pinion, 5 which meshes with the rack, 8, carried on the wheel z. A bar, 15, connects the free ends of the arms 3", t. Said arm 16' turnsa shaft, t which carries at its lower end a short arm,t having a roller, g at its outer end which makes contact with and is actuated by the cams on the formers, e, and causes pinion, s and rack, 8 to mesh and actuate said gear and worm. Said rosin-supplying mechanism and the maudrels, d, are placed so as to bring the roller, (1 in contact with a reciprocating cam, q, on the outer, ends of two loose and headed pins passing through the outer one of a pair of formers, e, which are countersunk for said heads. When a canbody is held by the formers said pins are pushed and held in their outer position by such can-body, then the cam, q, pushes the roller 1 outward thus throwing the arm, t, inward and causing the pinion, s, to engage the rack, s", and thus set said train of gearing and worm, .9 into action. An arm,p, also attached to some part of the frame or other stationary part of the machine, succeeding the arm, 3, carries the solder-feeding mechanism, the solder, preferably, being in the form of a wire which is fed by a pair of duplicate grooved rollers, 13 on a pair of shafts with a pair of duplicate gear wheels, 19 at the other end of said shafts. A gear wheel, 19 meshes into one of said gear-wheels, p and to it is fixed a pinion, 12", which meshes into a rack, s", on the wheel a.

Loosely pivoted on the outer end of one of the shafts of the gears, 12, is an arm, 13', which expands at its outer end and carries the shaft of the wheels, 19 12", and a pin to which one end of a bar, q, is connected, its other end being pivoted to an arm, q, fixed to the shaft,

(1 which, at its lower end, has a short fixed arm, (1 with a roller at its outer end. Said roller, is moved by the cam, (1 when the latter is pushed to its outer position by a canbody in the formers and thus the solder-wire feeding mechanism is set into action in like IIO position, the heads of the pins which'hold it passing into the large slot of the mandrel, d, and thus no contact of either mechanism is made with said rack, 8 A cam, r, on the Wheel, 2, actuates the shears, r, to cut off the wire solder, p. The joint thus prepared is now touched by the hot soldering-bit, at, car-- ried in the compound arms, j, l, of which the I former is hinged to the disk, It, so as to play vertically, while the arm, Z, is hinged on the army, so as to play horizontally-on it; the joints of said arms being near each other. Said bit, it, is wed g'e-shaped near its lower end but its upper end is cylindrical and provided with a flange of which the surface which rests on the arm, I, is spheroidal, and its seat in said arm of corresponding form, and said arm is provided with fourlugs, tt,two on the vertical and two on the sloping sides of said bit and on each side of one of the former lugs are lugs, 11., on the bit, it, spaced so as to allow to it a slight axial motion to accommodate itself to the circular motion of the joint of the can.

Between the outer end of the forked arm, Z, is an eccentric the shaft of which runs in a box in the arm,j, and on the-lower end of the shaft there is a pinion, Z which plays in therack-teeth m, ofthe circular cam, 'm. This mechanism gives a longitudinally recip rocating motion to the bit, min addition to its other adjusting motions. Near theouter end of the arm,j, there is a large opening in which said bit has free play. The arm, j, rises vertically at its outer end and has a flange through which passes an adj usting-screw, j

upon a plate, 7' held and fastened to said upright end bya bolt passing through a slot in it into said upright end and carrying at the lower end thereof a roller, j which runs on a cam-shaped track, m, and thereby said bit, n,is raised from and lowered to the work at proper time and place.

The bit, n, is a shell, heated from above by a burner, o, supplied with air through the upper pipe, '0', and with gas through the lower pipe, 12 The air and gas are supplied through the hollow shaft, 0, which is divided by a dia-' phragm, w, below which the gas is received through a tube, '0, held in the lower end of shaft, 0, in a stuffing-box the gas passing through holes into the pipes, 22 The pipe, 4), enters the upper end of the shaft, 0, through a stuffing-box and through holes in the pipe, 0, passes the air through the tubes, '2), into the burner, o. A ring, 2, is fastened upon the wheel, d. It is provided with short upright segments, 2, to which the racks, 5?, are attached.

When the joint is soldered the formers c release the can-body, through the action of the cams, 'i, and levers 6 and, shortly before finishin g a complete circle a cross-bar, y,

centrally pivoted on the arm y, attached to a post, I), enters the slot of the mandrel, d, and thus stops the can body and causes the mandrel to move out of it and the can-body to drop from the machine, finished, to receive its heads.

The formers to form the can-body on the mandrel are not indispensable as the canbodies, already formed, may be slipped onto the mandrels.

It will be observed that there are as many soldering-bits as there are mandrels but there is only one compressing-roller 0 and one fluxing and solder supplying mechanism used, or

necessary. The advantages thus attained over preceding devices are apparent, and at the same time it is easy to see that a single solderingbit may be made to operate on succeeding cans, as do the fluxing and other devices mentioned.

The advantages gained by giving an'unintermittent motion to my mandrels, are: that it requires much less power to work the machine, therefore it can be built lighter and cheaper and be run at a far higher speed than when it has to move and stop step by step for the various operations and, finally,

I because intermittent and jerky motions injure the freshly soldered joint. I avoid, in a great measure atleast, all the above difficulties.
